The sealing material fitted around the edges of a recreational vehicle’s entrance serves as a barrier against the elements. This pliable barrier prevents water, dust, insects, and drafts from entering the vehicle, ensuring a comfortable and protected interior environment. For example, a common type is made from durable rubber and adheres to the door frame.
A properly sealed entryway is essential for maintaining a comfortable temperature inside a camper, reducing energy consumption required for heating and cooling. It also protects the vehicle’s interior from moisture damage, which can lead to mold, mildew, and structural deterioration. Historically, these seals were simple felt or foam strips, but advancements in materials science have led to more durable and effective options like EPDM rubber and silicone. These modern materials offer superior resistance to UV rays, temperature fluctuations, and compression, ensuring a longer-lasting seal.
